A fully configured motor drive inverter reference design that delivers improved levels of performance and flexibility for a variety of industrial and battery-powered applications, the EPC91200 is intended for 3-phase brushless DC (BLDC) motor drive applications and features the EPC2305, a 150 V 3.0 mΩ RDS(on) GaN FET.
The EPC91200 supports wide voltage ranges from 30 V to 130 V, making it suitable for 80 V and 110 V battery systems commonly used in industrial automation, agricultural machinery, and material handling equipment like forklifts.
Key highlights include:
High Current Capacity: Supports up to 60 Apk (40 ARMS) maximum output current with a switching frequency of up to 150 kHz.
Enhanced Efficiency: Optimised PCB layout and advanced GaN technology reduce resistance and heat generation for improved performance.
Integrated Features: Includes current sensing, voltage monitoring, overcurrent protection, and temperature sensing for robust operation.
Compatibility: Works with multiple controller boards from leading manufacturers like STMicroelectronics, Texas Instruments, and Microchip.
The reference design streamlines the development process with features tailored for quick deployment and evaluation. Its compact design (130 x 100 mm) includes a pre-configured shaft encoder/Hall sensor interface and supports Field-Oriented Control (FOC) techniques.
Engineers can also easily measure critical signals and optimise system performance using built-in test points.
“With the EPC91200, we’re providing engineers with a versatile, off-the-shelf motor drive solution, showcasing the efficiency, reliability, and adaptability of GaN technology in modern power systems,” said Alex Lidow, CEO of EPC.
Reference design boards and devices are available for immediate delivery from Digi-Key.
